This review summarizes recent research on using PROTACs as a therapeutic strategy for brain tumors, focusing on their mechanism, benefits, limitations, and the need for optimization. The review draws from a comprehensive search of peer-reviewed literature, scientific databases, and clinical trial databases. Articles published up to the knowledge cutoff date up to 14 April 2023 were included. Inclusion criteria covered PROTAC-based brain tumor therapies, including preclinical and early clinical studies, with no restrictions on design or publication type. We included studies using in vitro, in vivo brain tumor models, and human subjects. Eligible treatments involved PROTACs targeting proteins linked to brain tumor progression. We evaluated the selected studies for methodology, including design, sample size, and data analysis techniques. A narrative synthesis summarized key outcomes and trends in PROTAC-based brain tumor therapy. Recent research shows PROTACs selectively degrade brain tumor-related proteins with minimal off-target effects. They offer enhanced potency, selectivity, and the ability to combat resistance compared to traditional inhibitors. PROTACs hold promise for brain tumor treatment offering advantages over traditional inhibitors, but more research is needed to refine their mechanisms, efficacy, and safety.

Rat IVD NPCs were cultured in vitro and transfected with miR-124-3p mimics, miR-124-3p inhibitor, oe-CAPN1 and their negative controls. The mRNA levels of miR-124-3p and CAPN1 were assessed by RT-qPCR. Cell proliferation, apoptosis and migration were evaluated by CCK-8, flow cytometry and Transwell assays. Levels of CAPN1 protein, apoptosis-related proteins (BAX, Cleaved-Caspase3, BCL-2) and extracellular matrix (ECM) proteins (Collagen II, Aggrecan, Fibronectin, Collagen I, matrix metalloproteinase [MMP]-13) were determined by Western blot. The target binding relationship between miR-124-3p and CAPN1 was verified by dual-luciferase assay. miR-124-3p overexpression facilitated NPC function and the maintenance of ECM homeostasis, as evidenced by increased NPC proliferation and migration, decreased apoptosis, elevated apoptosis-related protein BCL-2 level, diminished BAX and Cleaved-Caspase3 levels, reduced levels of ECM homeostasis-associated factors Collagen I and MMP-13 proteins, as well as raised levels of Collagen II, Aggrecan and Fibronectin proteins. Conversely, miR-124-3p knockdown brought about the opposite results. miR-124-3p targeted CAPN1.

Exosomes derived from CAFs have emerged as important mediators of intercellular communication in the tumor microenvironment, contributing to cancer progression. Therefore, it is essential to further investigate the mechanisms by which CAF-derived exosomes regulate NSCLC. CAFs promoted NSCLC cell proliferation, invasion, and migration, while also suppressing radiosensitivity. We observed an upregulation of FAM83F expression in both NSCLC cells and NSCLC cells treated with conditioned medium from CAFs. Notably, CAF-derived exosomes were found to transfer FAM83F to NSCLC cells, thereby enhancing the malignant properties of the cancer cells. In contrast, FAM83F-deficient CAF-derived exosomes exerted inhibitory effects on NSCLC cell proliferation, invasion, and migration, while also sensitizing the cells to radiotherapy. FAM83F was found to interact with KIF23 in NSCLC cells, and the overexpression of KIF23 attenuated the effects induced by FAM83F-deficient exosomes in NSCLC cells. Moreover, FAM83F-deficient CAF-derived exosomes were effective in inhibiting tumor formation <i>in vivo</i>.
